The mass of the rock of gibraltar is 1.78 • 1012 kilograms. the mass of the antarctic iceberg is 4.55 • 1013 kilograms. approximately how many more kilograms is the mass of the antarctic iceberg than the mass of the rock of gibraltar? show your work and write your answer in scientific notation.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
